Abstract: Computer methods and systems provide management of payload data represented by electronic tokens. Applications may relate to asset-backed fungible tokens as well as non-fungible tokens. A payload data file may be added or kept current after initial token genesis by specifying, in token data, a pointer (e.g., as either a TXID specifying a wallet address as an endpoint, or as the wallet address) to one or more transactions that carry, such as in an OP_Return field, a link to a linking payload or to the added or current payload data file. A single transaction specifying the wallet address may thus update or enhance any number of electronic tokens linked to the payload data file.

Abstract: A method including sonication of a yogurt culture produces desirable texture and yield characteristics. An apparatus for producing yogurt from milk includes a sonicator for controlling texture.

Abstract: An event marking device marks the real time at which notable events occur. When a notable event occurs, a user causes the event marking device to generate a trigger signal. The event marking device includes a real-time clock. When the user causes a trigger signal to be generated, a microcontroller of the event marking device reads the real-time clock and writes trigger event data to a memory indicating a real time at which the trigger signal was generated. The event marking device outputs the trigger event data to an external device.
